One of the most critical roles of GISRS is in the development of influenza vaccines. Twice a year, GISRS experts convene to review data on circulating influenza strains and recommend which strains should be included in the upcoming season's vaccine. This recommendation is based on the latest surveillance data, antigenic characterization, and genetic sequencing of influenza viruses. The timely and accurate data provided by GISRS ensures that the vaccine is as effective as possible in preventing illness and reducing the impact of influenza.
